2018 Ford Focus Steering Rack — Purpose, Care and Replacement

Based on technical sources, a steering rack is absolutely relevant to, and fitted on, the 2018 Ford Focus. The Ford Workshop Manual (2018 Focus, Section 211-04A Steering System—Electric Power-Assisted Steering) specifies an electric rack-and-pinion steering gear with an integrated assist motor and control unit. Ford’s parts catalogue lists a “steering gear—rack and pinion (electric)” for this model, and general repair data from Haynes and Autodata covering 2011–2018 Focus models confirms the same EPAS rack layout.

On a 2018 Focus, the steering rack’s job is to convert the driver’s steering wheel input into precise side-to-side movement of the tie rods, turning the front wheels. Because it’s EPAS (electric power-assisted steering), there’s no hydraulic pump or fluid—assist comes from an electric motor built into the rack, controlled by the Power Steering Control Module (PSCM). That means lighter weight, better fuel economy, and fewer fluid leaks to worry about.

As part of routine servicing, a workshop will typically check for play in the inner and outer tie rods, inspect rack boots for splits, listen for clunks over bumps, and verify there’s no looseness at the steering wheel. They’ll also keep an eye on wheel alignment and tyre wear patterns—uneven wear can hint at rack or tie-rod wear. Because it’s an electric unit, battery health and charging performance matter, low voltage can trigger steering warnings.

If a replacement rack is needed, expect the subframe to be partially lowered for access, followed by a wheel alignment and calibration procedures with a scan tool (steering angle learn and PSCM initialisation). Correct torque on subframe and rack fasteners is critical. Many owners opt for a quality remanufactured EPAS rack to keep costs sensible, provided it includes updated electronics and fresh inner tie rods. There’s no power-steering fluid to change on this model, but dust boots and tie-rod ends remain wear items over the kilometres.

• Watch for: EPS warning light, heavy or inconsistent steering effort, clunks on turn-in, vagueness on centre, or rapid inner/outer tyre wear.
• Good practice: keep tyres correctly inflated, rotate on schedule, check alignment after suspension work, and ensure the battery/charging system is in top nick.

Popular questions about 2018 Ford Focus steering racks

Does the 2018 Focus use hydraulic power steering fluid?
It doesn’t. The 2018 Focus uses an EPAS rack, so there’s no hydraulic pump, hoses, or fluid reservoir to service. If fluid is found near the rack, it’s likely engine oil or gearbox fluid from elsewhere, or grease from a split tie-rod boot.

What are common signs the steering rack or tie rods are worn?
Tell-tales include a knock over bumps, free play at the wheel, a pull or wander, uneven tyre wear, or an EPS warning. Inner tie rods often show up as looseness on centre, while outer ends can produce clunks during low-speed turns. A technician can confirm with a lift-and-check.

How much does replacement usually cost and how long does it take?
In AU/NZ workshops, a typical EPAS rack replacement on a Focus can run in the ballpark of $1,200–$2,300 including parts and labour, depending on whether a new or reman rack is used. Labour is commonly around 4–6 hours, followed by alignment and electronic calibration.
